In microwave GaAs MESFETs, carrier transport is a strong function of carrier energy. When illuminated, the carrier energy and carrier distribution inside the device are substantially affected by the incident optical energy. To account for these effects an accurate model based on the energy formulation of the transport equation coupled with optical energy conversion equations is used [1-2]. This model is used to investigate the optimum design of optically controlled MESFET structures considering the trade -off between the degradation in electric characteristics and the improvement in photoelectric conversion efficiency. Time domain simulations show the significant effect of electrode spacing, specifically, the drain-gate separation.
